计算了7颗类太阳恒星(带有类似太阳的行星系统)的大气参数和多种金属元素的丰度，所有样本星的金属丰度平均值为0.101，其中HD98230的值为-0.271，相对其余6颗星的值小很多(其余6颗星的平均值为0.184)，比银盘附近类太阳星的平均值([Fe/H]≈-0.3)相对较高.计算结果表明行星系统的形成与恒星的富金属丰度存在着一定的联系.

Atmospheric parameters and abundance of tens of elements forseven stars which have Sunlike spectrum type and planet system are calculated. The mean metallicity of these stars is 0.101, including a star named HD98230(whose value is -0.271, much lower than that of the rest). The metallicity of other six stars is 0.187, which is much higher than the mean value([Fe/H]≈-0.30) of F & G type stars in the Galactic disk. This result shows a certain correlation of the formation of planet system with the rich metallicity of the parent star.
